Answer 1

I'm by far no jQuery expert but maybe something like this....untested of course

jQuery

$(document).ready(function() {

    $('#delete').click(function() {

        var table = $('#table').val(); //where #table could be an input with the name of the table you want to truncate

        $.ajax({
           type: "POST",
           url: "truncate.php",
           data: 'table='+ table,
           cache: false,
           success: function(response) {
                alert('table dropped');
            },
            error: function(xhr, textStatus, errorThrown) {
               alert('request failed');
            }
        });

    });
});

PHP (truncate.php)

    try {
        // create a new instance of a PDO connection
        $db = new PDO(DB_TYPE.':host='.DB_HOST.';dbname='.DB_NAME, DB_USER, DB_PASS);
        $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }
    catch(PDOException $e) {
        // if the connection fails, display an error message
        echo 'ERROR: ' . $e->getMessage();
    }

    $table = $_POST['table'];

    $sql = 'TRUNCATE TABLE '.$mytable;

    $stmt = $db->prepare($sql);
    $stmt->execute();
